The best way to practise for the JAMB CBT on your phone is to take short timed sets of real past questions most days, sit one full JAMB-style mock a week, and spend as much time reviewing your wrong answers as you spend answering. Your phone is enough for most of that work, as long as you practise under a timer and keep a record of the topics you keep missing.
Why phone practice works
Most UTME candidates carry a phone everywhere, so it is the device that turns spare minutes into practice: the bus ride, the break between lessons, the hour before bed. What matters is not the screen size but the habit. Ten focused questions every day beat a long session once a fortnight, because you see more topics more often and you forget less between sessions.
Phone practice also makes reviewing easy. When an explanation sits right under the question, you are more likely to read it than when the answer is at the back of a textbook.
Set up your phone for practice
A few minutes of setup makes every session count:
- Pick one place for all your practice. Use one app or site for timed sets and mocks so your scores and weak topics are tracked in one place. On DeeepSolve, start from the JAMB past questions hub and choose a subject.
- Turn on a timer for every set. Untimed practice feels productive but hides your real speed.
- Silence notifications while you practise. Put the phone on Do Not Disturb for the length of the set.
- Keep a notebook for an error log. One line per wrong answer: subject, topic, what went wrong.
- Plan for weak network days. In the DeeepSolve Android app you can download question packs and keep practising without data.
A weekly CBT practice routine
Use a routine you can keep even in a busy school week. Here is one that works for most students:
| Day | What to do | Time |
|---|---|---|
| Monday to Thursday | One timed set of 20 questions in one subject, then review | 30–40 minutes |
| Friday | Redo every question from your error log for the week | 30 minutes |
| Saturday | One full JAMB-style mock in all four subjects | Full mock length |
| Sunday | Rest, or light reading on the weakest topic from the mock | 20 minutes |
Rotate the subject each weekday so all four get attention. If one subject is far behind the others, give it two weekdays instead of one.
Choosing the questions
Start with your weakest subject's past questions, one year at a time, so you meet the kinds of questions examiners like to repeat. For example, work through JAMB Mathematics past questions topic by topic, then try a full paper such as the JAMB English Language 2024 paper under time. For science subjects, JAMB Physics 2023 past questions is a good full paper to test your speed on calculations.
Practise the CBT controls
Speed in the CBT is not only about knowing the answer. It is also about moving through the screen without hesitating.
- Learn to skip and come back. If a question takes too long, move on and return to it at the end.
- Check for unanswered questions before you submit. They are easy to miss on a small screen.
- Use a computer when you can. The DeeepSolve CBT mode on the web supports the keyboard shortcuts of JAMB-style CBT (A to D to choose an option, N for next, P for previous, S to submit), so a few mocks on a laptop or a cybercafé computer make exam day feel familiar.
Review every mock properly
The review is where your score actually improves. After each set or mock:
- Open every question you got wrong or skipped.
- Read the explanation, or ask the AI tutor to walk you through it, and find the exact step where you went off track.
- Write the topic in your error log.
- Redo the question a few days later without looking at the answer.
If the same topic shows up in your log three times, stop doing mixed questions for a day and study that topic properly, then come back to timed practice. The guide to using past questions for WAEC explains this review method in more detail, and it works the same way for the UTME.
Common mistakes to avoid
- Practising without a timer. You will feel ready and then run out of time in the real exam.
- Only reading answers. Reading a solution is not the same as being able to produce it under pressure.
- Skipping your weakest subject. It is the subject with the most room to improve.
- Leaving computer practice to the last week. A few computer mocks spread over your preparation are worth more than one the night before.
For things that change every year, such as registration and exam schedules, always check JAMB's website rather than social media posts.
Frequently asked questions
Can I prepare for the JAMB CBT with only a phone?
Yes. A phone is enough for timed past-question practice, reviewing explanations and tracking weak topics. If you can get a laptop or desktop now and then, use it for a few full mocks so the keyboard and screen feel familiar on exam day.
How often should I take a full CBT mock?
Once a week is a good rhythm for most students. Spend the other days on short timed sets by subject and on reviewing the questions you got wrong in the last mock.
Is phone practice the same as the real CBT centre?
No. The real exam runs on a centre computer with a mouse and keyboard. Phone practice builds speed, accuracy and topic knowledge, and a few mocks on a computer cover the difference.
What should I do after each mock?
Go through every wrong or skipped question, work out where you went wrong (read the explanation or ask the AI tutor), write the topic in an error log and redo those questions a few days later without looking at the answer.
